The error is in the second step they subtracted 3 from both sides but it was a 3x, which you can not do.
Correction.
9x+18+3x=1
12x+18=1
12x=-17
x=-17/12
You can use this equation to find the axis of symmetry or the vertex of the quadratic equation as long as it is in standard form
X= (-b/2a)
The answer is x=2
56 + 32 = (8 x 7) + (8 x 4) = 8(7 + 4) (Answer C)
